CBEAM-SEPARATOB.

To aZZ whom 'it may concern vBe it known that I, (luenen A. YEATTER, a citizen 'of the United States, residing at `Monroein the county of Monroe and State forth, means for attaching the Sallie to the mouth of a bottle in an air tight manner and to mount in said means -an escape tube for the cream that is readily adjustable and at the same time mounted in an air tight manner in the device. j

Other objectsof the invention not herein specifically stated will be set out in fullin the following specification, pointed out particularly in the accompanying claim andillustrated 1n the drawings whlch VVshows a Specincation ofiLettex-s Patent.

4drive the same out of the bottle through a g er object of the inventionl is to provide in a cream separator of the type set of thin sheet metal 'fiat on top and having its edge folded against the underside ofthe vclosure and then bent outwardly as at 11 to form an exterior concaved groove in the surface of the depending portion 12 of the closure. Within the aforesaid groove. is placed a resilient ring 13 of such size as to fit snugly within the shouldered portion-aof the bottle and form an air tight joint between the bottle and the closure 10.

lRisin r 4:from the center of the closure 10 is a nec i 14 tapering outward slightly as it rises and being of suflicient length to snugly seat a stopper 15 of cork, rubber or other eompressible material. The neck 14 is preferably integralwith the closure and may be Patented J an. 27, 1920.

Application filed November 15, 1916. Serial No. 131,498.

formed by pressing the center of the disk outwardly, or securing lthe neck in place by soldering or welding as may be most expedient. The, bore of the neck 11 communicates through the closurel() as at 16 with the interior of the bottle.

Vertically through the center of the stopper 15 is anv openine 17 in which is snugly .fitted a tube 18 of glassv` metal or other rigid material, said tube being movable longitudinally in the opening 17 but by reason of the tapered form of the stopper 15 and neck 14, said stopper is pressed air .tight against the neck and the tube when forced downwardly into said neck. The tube 18 is preferably straight except at its ripper end which may be curved as at 19 ou a half u J Y clrcle to deliver the cream from the bottle A intoa suitable receptacle for the same.

Secured to the closure 10 at one side of the neck 14 is an upright nipple 20 having a' central perforation 21 that opens through the closure 10 and which may be corrugated on its outer surface to receive and hold in an air tight manner one end of a rudder or other flexible tube 22, the opposite end of which tube is connected to a hollow stem on one end of a compressible, bulb 24. 'l'he bulb 24 is of a type .such as is used with syringes and has an inlet valve 25 at one end and an outlet valve 2o at the opposite end, the latter valve being within a casing y27 from which the stem 23 projects. .'lhe valves 25 and Q6 are here shown as of ball type lbut may if desired be made in any other way that is most convenient and are mounted in their casing in such manner that compression of the bulb will force air iu one direction only through the tube. QQ.

Constructed as described, the closure 1() is fitted in the mouth of the bottle A, by seating the ring 13 in the shouldel'a of the. bottle and the tube 1S moved up ordown in the stopper 15 as desired until its lower open end is at the lineof' separation between the milk and thecrearn within the bottle. The, stopper 15'is then forced downwardly into the neck 14. to seal the tube 18,:iir tight.- The.

bulb 24 is now compressed and air forced l 'may be in the mouth of another l due to the fact that the bottles are more or A .the cream a tho bottle and the operation repeated. By means of the separator just described, cream can be quickly and thoroughly removed from 'the surface of milk Within bottles without less shaken while being transported and the cream is thrown agalnst. the sides of thebottle at the mouth and I claim: y

In a device of the character described, the combination of a flat disk-like closure said closure having its outer peripherybent inwardly and then downwardly and outwardly, thus, forming a curved support` upon the shoulder a.

ing flange, the lower edge of which is oil'set l Witnesses:

inwardly from the outer portion of the disk like closure, a yieldable ring carried byA said flange, the outer surface of the ring extending outwardly vbeyond said Harige, whereby theclosure mayrest upon a milk bottle with the ring engaging the channeled portion of the milk bottle and the flange eX- tending into the milk bottle, an integral conical neck rising from the centralportion of said closure, a tapering stopper removably inserted into saidneck, a tube carried by said stopper, an upright nipple secured to said closure and rising contiguous to said neck, a flexible tube for fitting over said nipple, whereby the tube will be gripped bef` tween said .nipple and neck 'to be held against accidental displacement and apumpingmeans connected to the outer Aend of said tu In testimony whereof aiix my signature in presence of two. witnesses. l `GrIORGrE A. YEATTER.
